A visual and intelligent judgment system and method for hot rolling temperature of steel coil

Abstract

The invention discloses a visual and intelligent steel coil hot rolling temperature determination system and determination method, belonging to the technical field of hot rolling. The hot-rolling temperature determination system of the present invention includes a hot-rolling primary system, a hot-rolling secondary system, a temperature detection device, an encoder, a data acquisition machine, and a QMS management application platform. Order information, according to the steel coil output event information, perform differential configuration and evaluation tolerances in the server of the QMS management application platform, and transmit the hot-rolled temperature curve data of steel coils collected on site to the QMS management application platform, through the QMS management application platform The platform develops the imputation function and formulates the quality factor to analyze and process the hot-rolling temperature curve, and automatically judges whether the hot-rolling temperature of the steel coil to be tested is qualified, thereby greatly reducing manual query work and improving work efficiency and judgment accuracy.

Description

technical field [0001] The invention belongs to the technical field of hot rolling, and more specifically relates to a visual and intelligent judgment system and method for hot rolling temperature of steel coils. Background technique [0002] The temperature control of hot rolling is the core of hot rolling process control, and the two most critical temperatures are the exit temperature of finishing rolling (abbreviated as: FDT) and the entrance temperature of coiling (abbreviated as: CT). The fluctuations of these two temperature controls not only directly affect the structure and performance of the hot-rolled sheet, but also affect the thickness accuracy, width accuracy, and plate shape of the product. As the customer's judgment range for product performance becomes more and more stringent, the concept of process steel judgment is also gradually formed. As an important part of the entire product production chain, the control of hot rolling temperature has gradually been i...
